The toothed wheel 55 of thd sawing device, which meshes with toothed wheel 28, is revolved with a speed equal to the ditl erenee between the speed of said toothed wheel 23 and the working table 10. The toothed wheel of the sawing device takes along the spindle 58 through the intermediary of the friction cone 56 which by means of the spring (31 is pushed .into the conical clutch 57 of said spindle. This spindle 5S and the toothed wheels 50 and GO keyed upon the same transmit the revolving motion to the toothed wheels 28' and 31 whiclnin their turn, more the oppositely arranged clamping jaws wand 30 for. the nuts.

Suppose that the nut is clamped in lietween said jaws 1n the direction of its longit-u'dinal a.X1s; in this case the upper clampmg aw 30 with the weight 49 will press upon the hut so that the same turns around a longitudinal axis together with the clamp and the saw blade 86 pressed the met through the action of the V ing aw aga nst l spring-92, willsaw the shell owing to the :re'volving motion of the working table 10.
